Novel insights into K(+) selectivity from high resolution structures of an open K(+) channel pore

K(+) channels are highly selective for K(+) over Na(+). Here we present several crystal structures of the MthK K(+) channel pore at up to 1.45 Å resolution. The MthK selectivity filter maintains a conductive conformation even in the absence of K(+), allowing the channel to conduct Na(+). The high re...
